The Rain Particles Renderer blends the texture with the background scene using an Add operation. This requires only one texture channel (Red).

You can use a free database of rain streaks textures, such as http://www1.cs.columbia.edu/CAVE/databases/rain_streak_db/rain_streak.php.

Choose the texture carefully to achieve an ideal final result.
Mipmapping
Mipmapping is enabled when the texture already contains a mipmap chain. For example, a DDS with mipmaps.

MipMaps (also MIP maps) are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the same image. They are designed to increase rendering speed and reduce aliasing artifacts. |
